`center`	the center of map, you can use diameter, nomination or address
`zoom`	map zoom, it is 1~14 integer
`size`	rectangular dimension in map
`format`	image format
`crs`	Enter the EPSG coordinate system code value. "EPSG:4326" is default
`baselayer`	you can select "satellite" or "default". default is general map
`markers`	data.frame with first column longitude, second column latitude, markers displayed in map
